Abstract :
This paper proposes a novel programmable power monitor chip. With only three program pins and without any off-chip devices, the chip has 36-program states by taking different connections for the 3-program pins. The chip can monitor the voltage from 1.5 v to 5.0 v with 0.1 v step. Special SH circuit and current limited digital blocks are employed to achieve ultra low quiescent power. The implementation is based on 2M1P 0.5 μm mixed signal process, the die area is 0.24mm2, and the quiescent current is only 3 uA.
